BeamSync

Offline-first desktop app for fast peer-to-peer large-file transfer over the local network via QR code.

Desktopfree

BeamSync is a cross-platform desktop app for transferring large files directly between devices over a local network at full LAN speed, with no internet connection, cloud service, or account needed. A phone or other device can join a transfer instantly by scanning a QR code, without installing any app, while the desktop side auto-detects the network and configures firewall rules as needed. It's aimed at people who regularly move large files between a phone and a desktop on the same network.
